First ever parkour injury

I suffered from an injury yesterday. Unfortunately, the beam I precisioned onto was a bit unstable, thus, forcing me to plunge back and land on my butt. I also noticed my back was aching about twice as much as my rear end.

Today the pain has slightly gone away since the first day. I'm thinking of taking a break from parkour for one or two days. I'll then start to get back into parkour starting with few hour jogs and start building my way back up to doing everything else.
